VIBRATION MEASUREMENT IN FULL-SCALE FIELD TEST OF 6 STORY WOOD FRAMEWORK WALL SYSTEM UNDER EXTERNAL EXCITATION

Abstract

Vibration measurement has been performed for a full-scale field test of 6 story wood framework wall system under external excitation. A vibration generator was placed on the ground near the target building. 20 MEMS acceleration sensors were installed inside and outside of the building to monitor the propagation characteristics of vibration in the superstructure and foundation. It is concluded that the rocking motion of foundation becomes predominant rather than the deformation of superstructure when the height/width ratio is large.
